Problems solved by technology

[0002] The motor is composed of two main parts, the stator and the rotor. In the past, the motor stator was generally insulated by inserting insulating paper. This structure requires workers to fold the insulating paper first, and then insert the formed insulating paper into the slot of the motor stator. In the middle, the wire is wound on the insulating paper. Using this structure is time-consuming and laborious, and the insulation effect is not good. The insulating paper is easily damaged by friction, and it will bring great inconvenience to the winding of the motor behind.

Embodiment

[0023] Example: such as Figure 1 to Figure 4 As shown, a brushless motor stator, the stator includes a cylindrical yoke 13 made of laminated steel plates, along the inner surface of the cylindrical yoke 13 radially provided with a plurality of protrusions 14 toward the center of the yoke At the end of the protruding portion 14, there are line retaining portions 15 extending to both sides of the protruding portion 14 respectively. There is a gap 16 with the same width between them, the protruding part 14 is used as a winding support for the winding coil, and the retaining part 15 can be used to limit the coil on the protruding part 14, preventing its deviation from contacting the rotor; all retaining parts The inner surface 18 of the wire portion 15 is formed with a rotor accommodating cavity 17 into which a rotor can be inserted.

[0024] Two insulating skeletons with the same shape are inserted on the front and back sides of the cylindrical yoke 13. Several winding parts ar...

Abstract

The invention discloses a brushless motor stator, which comprises a cylinder-shaped yoke. A plurality of radial projections are formed along the inner surface of the cylinder-shaped yoke and towards the center of the yoke; block wire parts formed at the end parts of the projections respectively expand towards two sides of the projections; rotor accommodating chambers are formed on the inner surface of the block wire parts; two insulation frame works with the same shape are inserted in the positive and the negative of the cylinder-shaped yoke; a plurality of winding parts are arranged on the insulation frame works, and the winding parts can be combined with the projections and coat on the outer surface of the projections; and coils are wound on the winding parts. The insulation frameworks formed by module compressing are inserted into stator grooves in advance to ensure that the insulation frameworks are combined together with the stators, and then the coils are wound at the winding parts of the insulation frameworks. The invention has the advantages of saving labor and time, having wear resistance, and greatly improving insulation effect, compared with the prior art.

Description

technical field [0001] The invention relates to a brushless motor stator with good wear resistance and good insulation effect. Background technique [0002] The motor is composed of two main parts, the stator and the rotor. In the past, the motor stator was generally insulated by inserting insulating paper. This structure requires workers to fold the insulating paper first, and then insert the formed insulating paper into the slot of the motor stator. In the middle, the wire is wound on the insulating paper. Using this structure is time-consuming and laborious, and the insulation effect is not good. The insulating paper is easily damaged by friction, and it will bring great inconvenience to the subsequent motor winding. Contents of the invention [0003] The present invention aims at the deficiencies of the above-mentioned prior art, and provides a brushless motor stator which is durable and has good insulation effect. The insulating frame adopting compression molding can ...
